GENERATOR OR MOTOR SUSPENSION.

SPECIFICATION forming part Of Letters Patent No. 746,610, dated De embe8, 1903.

Application filed February 24, 1903. Serial No. IA LBOZ. (No model.)

To all whom it may concern.-

Be it known that we, MONTGOMERY WAD- DELL, a subject of the King ofGreat Britain, and HENRY K. BROOKS, a citizen of the United States, bothresidents of the borough of Manhattan, city, county, and State of NewYork, have invented certain new and useful Improvements in Generator orMotor Suspension, of which the following is a specification accompaniedby drawings.

This invention is more particularly applicable to electrical machines,such as generators or motors, suspended from car-trucks, although theinvention may be used in any connection in which it is found suitable.

The objects of theinvention are toimprove upon means heretofore devisedfor suspending generators or motors from car-trucks or from othersupports which are liable to jar and vibration, and suitable provisionis afforded for cushioning the motoror generator in all directions.According to our construction a generator may have a certain movement ina vertical plane to guard against the shocks and jars incident togenerators suspended from car-trucks and the generator may be swung toand from the driving-shaft or car-axle to take up the stretch of thebelt when a belt is used for driving purposes, and provision is alsothus afforded for compensating for irregularities and unevenness in thedriving-pulleys with a belt-drive.

Another object of this invention is to enable the generator to have alateral movement relatively to the car-frame.

Further objects of the invention will hereinafter appear; and to theseends the invention consists of apparatus for carrying out the aboveobjects embodying the features of construction, combinations ofelements, and arrangement of parts having the general mode of operationsubstantially as hereinafterfully described and claimed in thisspecification and shown in the accompanying drawings, in which Figure 1.is a side elevation, partly in section, of a truck provided withapparatus embodying the invention. Fig. 2 isa plan view of the same.Fig. 3 is an end view looking at the front of the truck. Fig. A is anenlarged detail View of a portion of the apparatus. Fig. 5 is a planview of Fig. 4c, and Fig. 6 is an end elevation of the portion ofapparatus shown in Figs. 4 and 5 with the shaft removed.

Referring to the drawings, A represents the frame of the truck, providedwith the wheels B upon the axles O. In this instance a generator D issuspended from the truck, although a motor may be suspended by the samemeans. Suitable means are provided for driving the armature of thegenerator from the axle O, in this instance a drivingpulley E beingprovided upon the axle connected by the belt F with the driven pulley Gupon the armature-shaft H.

Suitable brackets H are provided upon the wheel-guards I for supportingthe transversely-extending beam J. According to this invention the beamJ supports the generator D and is suitably cushioned, as hereinafter tobe described. The beam J may also have movement transversely of thecar-truck for a purpose hereinafter to appear. The brackets Hareprovided with the sockets K, affording steps or bearings for the springsL, which support the boxes or frames 0 and in which are journaledrollers P. The transversely-extending beam J is supported upon therollers P and is of slightly shorter length than the distance betweenthe outer ends Q of the brackets H, so that said beam J may havemovement transversely of the car upon the rollers P. Suitable buffers R,which may be rubber blocks, are arranged within the brackets H, whilecushioning-rollers S, shown as rubber-covered bolts, are arranged in theboxes 0 and above the beam J. According to this construction the beam Jis cushioned in its movement transversely of the car, and it is alsocushioned vertically against the rollers S.

The weight of the generator D is carried by the beam J, so that thegenerator is cushioned against vertical shocks or jars by the springs L,which may be of any suitable character, shown in this instance as coiledsprings, although elliptical and other forms of springs may be utilized,as desired. The generator in this instance is hung in thesupporting-straps T, which are tight upon the transverse beam J. Thebeam J may rotate aboutits own longitudinal axis and, as stated, mayslide longitudinally on the rollers P. It will be seen, therefore, thatthe generator may have three independent movements, or, in other words,it may move vertically and horizontally, and it may also be rotatedabout the longitudinal axis of the beam J. The straps T are made fast tothe beam J in order to maintain the armature-shaft substantiallyparallel to the axle and cross-beams when the generator is moved to andfrom the axle O, and since the direction of the belt is transverse tothe axis of the beam J vertical movement of the generator may take placewithout affecting the tension on the belt F or causing it to slip uponthe pulleys.

The driven pulley G is provided with flanges V at each side, betweenwhich the belt F runs. As the driving-pulley E on the axle O shiftslaterally, the generator-shaft will also be shifted laterally to keepthe belt substantially in the center of both pulleys. For this reasonprovision is afforded for lateral movement of the generator.

Means are provided for adjusting the generator to and from the axle O,as shown, the screw-threaded rod W being connected to the generator atone end and extending through the support X on the truck-frame at theother end. A suitable spring Z is maintained in compression between thesupport X and the adjustable stop Y, which is provided with a handle.According to this construction the spring acts to cushion the generatoras it swings, and at the same time tends to force the rod W andgenerator away from the support X to maintain the desired tension uponthe belt F.

According to this invention the weight of the generator is utilized toprovide tension upon the belt. As shown, the generator is suspendedslightly out of the perpendicular in such manner that its Weight acts toprovide tension upon the belt F. It will also be seen that the ends ofthe beam J project over the Wheel-guards I, so that if for any reasonone of the supporting-brackets Q or spring L should break the end of therod J would rest upon the guard l.

Obviously some features of this invention may be used without others,and theinvention may be embodied in widely-varying forms.

,Therefore without limiting ourselves to the construction shown anddescribed nor enumerating equivalents, we claim, and desire to obtain byLetters Patent, the following:

1. The combination with a truck, of springs carried thereby, a beamsupported upon said springs and movable transversely of the truck, theends of said beam projecting over the wheel-guards of the truck, and amotor or generator operatively connected to the axle and suspended fromsaid beam, for substantially the purposes set forth.

2. The combination with a truck, of springs carried thereby, boxessupported on said springs, rollers journaled in said boxes, a beamresting upon said rollers and extending transversely of the car,wherebysaid beam may have movement in the direction of its length, and alsoabout its longitudinal axis, and a motor or generator operativelyconneoted to the axle and clamped tightly to said beam, forsubstantially the purposes set forth.

8. The combination with a truck, of a beam resiliently supported thereonand movable in the direction of its length transversely of the truck, amotor or generator operatively c011- nected to the axle and suspendedfrom said beam whereby the motor or generator may have both vertical andhorizontal movement, a flanged pulley on the generatowshaft, adriving-pulley on the axle and a belt connecting said pulleys, forsubstantially the purposes set forth.

4. The combination with a truck, of springs carried thereby, boxessupported on said springs, a beam supported on said boxes and extendingtransversely of the car whereby said beam may have movement in thedirection of its length and also about its longitudinal axis, and amotor or generator operatively connected to the axle and supported fromsaid beam, for substantially the purposes set forth.

In testimony whereof we have signed this specification in the presenceof two subscribing witnesses.
